[amp_mcq option1=”Create more electrical noise” option2=”Are likely to melt under excessive eddy current heat” option3=”Consume more power” option4=”Exhibit unwanted inductive and capacitive effects” correct=”option4″]<\/p>\n
The correct answer is D. Wire-wound resistors exhibit unwanted inductive and capacitive effects at high frequencies.<\/p>\n
Inductive effects occur when a changing current through a wire induces a magnetic field. This magnetic field can then induce a voltage in another wire that is close by. This can cause problems in circuits where high frequencies are present, as it can lead to unwanted signals being generated.<\/p>\n
Capacitive effects occur when two wires are close together. The electric field between the wires can then cause a current to flow between them. This can also cause problems in circuits where high frequencies are present, as it can lead to unwanted signals being generated.<\/p>\n
Options A, B, and C are incorrect. Wire-wound resistors do not create more electrical noise than other types of resistors. They are not likely to melt under excessive eddy current heat. And they do not consume more power than other types of resistors.<\/p>\n
In conclusion, wire-wound resistors are unsuitable for use at high frequencies because they exhibit unwanted inductive and capacitive effects.<\/p>\n","protected":false},"excerpt":{"rendered":"
